Sensor Types and Application

Air-Coupled Ultrasonic Sensors

Designed for non-contact inspections, these sensors transmit and receive ultrasonic waves through air—making them ideal for evaluating materials like composites, plastics, or delicate structures where traditional contact sensors may damage the surface. Common in aerospace, automotive, and food packaging applications, they allow rapid, high-frequency testing without the need for couplants.

Contact Ultrasonic Transducer

These versatile sensors are used extensively in flaw detection, wall thickness measurement, and weld inspection. Coupled directly to the test surface using gels or pastes, they deliver reliable performance in steel, aluminum, and other solid materials. Contact transducers are widely used in power generation, construction, pipeline inspection, and manufacturing plants.

Phased Array Ultrasonic Probes

Featuring multiple individually-controlled elements, phased array probes electronically steer, focus, and scan sound beams through materials—allowing detailed, multi-angle imaging of internal defects. Their ability to visualize complex geometries makes them indispensable for high-value inspections in nuclear plants, aerospace components, and pressure vessels.

Acoustic Emission Sensors

Engineered to detect high-frequency acoustic waves released during material deformation or cracking, these sensors enable real-time structural health monitoring. Applications include bridge fatigue analysis, tank integrity testing, and early-warning systems for pressurized equipment. Their high sensitivity helps detect damage before it becomes critical.

Piezoelectric Microphones

These microphones use piezoelectric crystals to convert acoustic pressure into electrical signals. Offering excellent frequency response and durability, they are ideal for precise sound measurement in laboratory environments, fluid systems, wind tunnels, and engine test cells. Their ruggedness makes them suitable for both research and field applications.

Broadband Hydrophones

Capable of detecting a wide range of underwater acoustic signals, broadband hydrophones are used in sonar calibration, marine life monitoring, subsea equipment testing, and naval research. With high sensitivity and wide dynamic range, they allow precise detection of pressure waves, even in deep ocean environments or turbulent waters.
